Patented J To all whom it may concern:

Be it known that I, H exam J. AMnnosoN, acitizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Gas-Producers, of which the following, together with the accompanying drawings, is a specification.

'lhe present invention relates to gas producers, and has particular reference to the introduction and distribution of the blast of air, or air and steam, used to support the combustion of the fuel contained within the main shell, or fuel supporting section, of devices of this class.

The herein described embodiment of my invention, is, in the present instance, shown and described in its application to a specific construction and arrangement of producer parts involving the assemblage and support of the blast devices and the fuel section upon the ash support or pan of the producer, which construction forms the subject matter of an invention fully set forth and described in an application for Letters Patent tiled by E. A. W. Jell'erics, December ll, 1914, Serial No. 877,0Ul. But while my invention is shown thus applied, by reason of its peculiar adaptability as an important, useful; and valuable improvement upon the invention covered by the aforesaid application of Jetferies, yet my invention is not to be limited in its use to the above or any other particular construction, except in so far as is determined by the scope of the aimexed claims.

The essential features of my invention are fully set forth in the following description, and illustrated in the accompanying drawings, in which-- l igure l is a vertical sectional View of the lower portion of a gas producer embodying my invention Fig. 2 is a plan view of the same, portions thereof being shown in a section taken in the plane of line 2-2, Fig. l.

Fig, 3 a detail view in perspective of the adjacent ends of two segments of an annular blast box. i

Like reference characters refer to like parts in the dillerent figures.

The nut 1 indicates the lower portion of a gas prt .ng chamber, inclosed within the wall or shall. 2 which constitutes the tee].

supporting section of the producer. he lower end of said shell, in accordance with app-rovetilpri ctice, opens into a concentric a support r pan 3, shown in the present inst-nape as rotatable, in accordance with "the aforesaid invention oi Jeiferies, serving for the support or? the shell 2 through the interposition of a hollow spider casing 4, having a pluralitylot radial blast. arms 5, the outer ends of which are dis posed in supporting-relation to the lower end of said shell. The casting is supported. upon a hollow casting 6, disposed conceit trically upon the finer or bottom oi the a a pan, and providing a communicating blast passage between the interior of said spid r casting and a blast inlet passage 7 Qlcflllig upwardly through the supportin floor if the producer and centrally through the bot tom of said ash pan.

The hollow spider castiru l preferably has a central aperture, not siown, with respect to which aspaced circular cap 8 is etfcctive in providing for an annular upwardl y directed jet of blast through the stair ter of the bed of fuel. Each hollow blast arm? 5 is formed along its top wall with an elongated opening or slit 9, with respect to which a spaced rectangular cap 10 is elicctive in providin for a pair of upwardly directed jets of blast through the fuel bed in substantially radial planes.v

in accordance with the present invention, the structure made use of in rigidly and securely connecting the lower end of the. shell 2 with the outer ends of the blast arms 5, takes the form of a sectional annular. member indicated as a whole by the numeral ll, the same presenting an extended upper wall 1 preferably inclined so as to lie normal to the flaring wall 2 thereby facilitating the erection thereon o. the brickwork l3 constituting the inner lining of said wall. Said annular member 11 comprises a plurality of segmental sections, corresponding in numher to the number of radial blast arms 5, in the present instance shown as three in number. For convenience of manufacture and assemblage, each section comprises apair of trough-like segments l4, l5, substantially U-shaped in cross section, and disposed end to end, with their adjacent ends in communieation through a joint preferably formed by a U- shaped flange 16 on the segment 1%.,

Figs. 2 and 3, which is received within the site ends 20 cast in each segment, Fig. 2,

whereby the necessity for a close lit between the segments of the member 11 exists only with respect to one half ofthe total number of points at which the ends of adjacent segments meet.

The-segment 14 of each section of the member 11 has an inwardly extended radially disposed nipple 2-1, leading from the chamber 19, and forming a connecting passage between said chamber and one of the blast arms 5. Each of said blast arms carries, beyond its open outer end, with which the associated nipple makes a joint, a shelf or projection 22, disposed in supporting relation to said nipple, and to which said nipple is suitably secured by bolts, rivets or the like. The support of the shell 2 upon the ends of the blast arms is thereby attained.

The lower walls 23 of the several segments 14 and have downwardly opening blast apertures 24; therethrough; said walls lie in a plane closely approaching the horizontal, and overhang the lower portion of the shell 18. By reason of this disposition of the walls 23, the tendency of theadjacent ash or incandescent fuel in the horizontal zone of said apertures 2-1 to be crowded by the weight of the superposed fuel bed into close contact with the under side of the walls 23,-

is materially reduced, with the result that a well defined space or pocket 25 is maintained in the neighborhood of said apertures 24, permitting an unimpeded passage of the blast therefrom.

- The construction above described affords an ideal distribution of the blast to the bed of fuel. In addition to the distribution afforded by the spider casting 4, fully described above, an annular series of blast jets are delivered adjacent the wall 2 of the producer, whereby all portions of the fuel bed are subjected to a substantially uniform permeation by the blast. The division of the annular member 11 in to'a plurality of separated segmental blast chambers 19, corre- -.sponding in number to the number of radial blast arms 5, insures the delivery of the blast entering each of said arms to one third of the fuel bed surface. For if the member 11 presented a continuous annular blast cham her, the tendency would be for the greater at portion of the blast to escape therefrom at masses :1. point or points where the fuel bed presented the least resistance tothe passage of the blast through the apertures 2t.

By the present construction each blast arm 5 and its communicating chamber 19 delivers substantially one third of the blast, whether or not the apertures 24 of its chamber are more or less obstructed by the ash or fuel than the apertures 24 of another chamber- 19.

I claim, 1. In a gas producer, a fuel shell, blast distributing means for the fuel therein, comprising hollow radially arranged arms having perferations for the delivery of blast within said shell, and a hollow-member conforming to the wall of said she I and in communication with the outer onus of said arms, and means for rotating said shell and hollow annular blast distributing member carried upon the ends of said blast arms and communicating therewith, and a fuel-containing shell superposed upon said member.

4. In a gas producer, a shell inclosing a bed of fuel, blast distributing means therein, comprising a member cooperating with the wall of said shell to provide a chamber on the inner side thereof, said member providing a bottom wall for said chamber in a plane substantially normal to. the wall of said shell, with a series of delivery apertures opening downwardly through said bottom wall, and means .for rotating said member and said shell in unison.

5. In a gas Producer, a shell inclosing a bed of fuel, blast distributing means therein, comprising ahollow member conforming to the wall 'of' said shell and having on its under side a wall extending inwardly of said shell, said-wall providing the blast delivery means from said member to said shell, whereby the obstruction of the blast by the mass of fuel is prevented, and means for rptating said member and said shell in unison.

6. In a gas producer, a shell inclosing a bed of fuel, blast distributing means therein comprising a hollow member conforming to the wall of said shell and overlying a portion of the same, whereby a space substantially free from fuel is formed below said member, said member providing a series of naaaaaa to the wall of said shell and composed of a I plurality of" independent hollow sections each communicating with one of said arms, means for delivering blast from each of said sections, and means for rotating said members and said shell in unison.

8. In a gas producer, a shell inclosing a bed of fuel, blast distributing means therein comprising a hollow member disposed centrally of said shell and having a plurality of hollow radial arms, and an annular member conforming to the Wall of said shell and composed of a plurality of independent hollow segmental sections each communicating with one of said arms, means for delivering blast from each of said sections, and means for rotating said members and said shell in unison. i.
